In the figure: 1 auxiliary device A piece, 2 auxiliary device B pieces, 3 supports, 4 needles, 5 clamping plates, 6 pinholes, 7 locks, 8 convex clamping blocks, 81 bosses, 9 concave clamping grooves and 91 tooth-shaped structures.
Detailed Description
The following detailed description of the present application is provided in conjunction with the accompanying drawings, and it is to be understood that the following detailed description is merely illustrative of the application and is not to be construed as limiting the scope of the application, since numerous insubstantial modifications and adaptations of the application will be to those skilled in the art in light of the foregoing disclosure.
Example 1
As shown in fig. 1-3, a medical multifunctional tendon suture assisting device is provided, which comprises an assisting device a block 1 and an assisting device B block 2 which are connected end to end, wherein grooves which are communicated with each other are formed in the assisting device a block 1 and the assisting device B block 2 to form a tendon accommodating cavity for accommodating broken tendons, a tendon clamp is arranged at the far end of the assisting device a block 1 away from the assisting device B block 2 and the far end of the assisting device B block 2 away from the assisting device a block 1, and the assisting device a block 1 and the assisting device B block 2 are connected in a telescopic manner through a clamping piece.
The tendon clamp comprises a needle head 4, a clamping plate 5, a bearing and a lock catch 7, wherein the lock catch 7 is hinged on one side edge of an auxiliary A block 1/an auxiliary B block 2, one end of the clamping plate 5 is hinged on the other side of the auxiliary A block 1/the auxiliary B block 2 through the bearing, and the other end of the clamping plate is fixed through the lock catch 7; the needles 4 are provided with a plurality of needles, and are fixed on the inner side wall of the auxiliary device A block 1/the auxiliary device B block 2 through a support 3, so that the tips of all the needles 4 are ensured to be positioned on the same plane. The tip of the needle 4 faces the lower surface of the clamping plate 5, a needle hole 6 is formed in the lower surface of the clamping plate 5 opposite to the needle 4, and when the needle is used, broken tendons pass through the needle 4 and the clamping plate 5 and are fixed in the auxiliary device under the cooperation of the lock catch 7, so that the positions of the broken tendons are stable and not loose.
The clamping piece comprises a convex clamping block 8 and a concave clamping groove 9 matched with the convex clamping block, a boss 81 is arranged on the side edge of the convex clamping block 8, which faces the concave clamping groove 9, a toothed structure 91 matched with the boss 81 is arranged on the inner side surface of the concave clamping groove 9, the toothed structure 91 is a unidirectional tooth, faces the notch direction of the concave clamping groove 9, the convex clamping block 8 is tightly and firmly matched with the concave clamping groove 9 through the clamping of the boss 81 and the toothed structure 91, the position stability of tendons is guaranteed, and the stability and safety of the operation process are realized.
When the suturing operation is carried out, the needle heads 4 on the two sides of the tendon are respectively inserted into the positions which are about 1.5cm away from the broken ends, the tendon is clamped by the lock catches 7, the doctor pulls the auxiliary device A block 1 and the auxiliary device B block 2 close together by both hands until the two hands are at satisfactory positions, the convex clamping blocks 8 are inserted into the corresponding concave clamping grooves 9, at the moment, the broken parts of the tendon are just positioned in the auxiliary devices, the suturing operation can be carried out by a single person, and the lock catches 7 of the tendon clamp are released after the operation is finished, and the auxiliary devices are taken out. The mode effectively realizes single operator operation of tendon suture operation, saves human hands, and has better single operator operation effect. Because the action position of the auxiliary device is about 1.5cm away from two sides of the broken tendon, other important tissues such as adjacent vascular nerves are all positioned outside the auxiliary device, thereby avoiding the operation side injury, the groove-shaped tendon accommodating cavity can also prevent the peripheral blood seepage from entering, realizing clear operation vision and improving the suturing quality of the tendon.
The foregoing examples illustrate only a few embodiments of the invention and are described in detail herein without thereby limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention.
